4 / 18 page Pin configuration STCS2A 4/18 2 Pin configuration Figure 2. Pin connections (top view) Table 2. Pin description Pin n° Symbol Note 1VCC Supply voltage 2 PWM PWM dimming input 3EN Shutdown 4 NC No connect 5 DRAIN Internal N-MOSFET drain 6 SOURCE Internal N-MOSFET source. Reference voltage is 100 mV. An external resistor between SOURCE and GND pins sets different current levels for different application needs 7FB Feedback input. The control loop regulates the current in such a way that the average voltage at the FB input is 100 mV (nominal). The cathode of the LED and a resistor to ground to set the LED current should be connected at this point 8 GND Ground 9 SLOPE Capacitor for slope control 10 DISC Load disconnection flag (open drain) exp-pad Internally connected to ground |
